  1. 1. Prepared By : Mehta Shashwat J.(08/IT/091)
  2. 2.  Material requirements planning (MRP) is a production planning and inventory control system used to manage manufacturing processes. Most MRP systems are software- based, while it is possible to conduct MRP by hand as well. It is an operations management tool that uses a computer to help manage materials and inventories. MRP is a concept of creating material plans and production schedules based on the lead times of a supply chain. However, even if you create an MRP-based plan based on an ideal factory model, problems may still actually occur.
  3. 3.  MRP is a tool deal with these problem ◦ What items are required? ◦ How many are required? ◦ When are they required?
  4. 4.  A forecast of what products need to be made in the next few months (also known as a Master Production Schedule). A recipe which tells you which materials are used, in what quantities, to build each product (also known as a bill of material). The time required to obtain or manufacture all products and materials (the lead times). The maximum amount that can be processed at any one time (the batch size). The on-hand stock balance of all your products and materials (also known as the inventory balance).
  5. 5.  If a small business has not maintained good inventory records or has not updated its bills of materials with all relevant changes, it may encounter serious problems with the outputs of its MRP system. The problems could range from missing parts and excessive order quantities to schedule delays and missed delivery dates. At a minimum, an MRP system must have an accurate master production schedule, good lead time estimates, and current inventory records in order to function effectively and produce useful information. Another potential drawback associated with MRP is that the systems can be difficult, time consuming, and costly to implement. Many businesses encounter resistance from employees when they try to implement MRP.
  6. 6.  Manufacturing resource planning (MRP II) is defined as a method for the effective planning of all resources of a manufacturing company. Ideally, it addresses operational planning in units, financial planning in dollars, and has a simulation capability to answer "what-if" questions and extension of closed-loop MRP. It is integrated planning of a companys material, equipment and people to meet the Business Plan. The integration requires that the same information (Sales Forecast, Bill of Material, stock records, actual works, purchase and customer orders etc.) is used throughout the Company.

  8. 8.  MRP II systems can provide: ◦ Better control of inventories ◦ Improved scheduling ◦ Productive relationships with suppliers For design / engineering: ◦ Improved design control ◦ Better quality and quality control For financial and costing: ◦ Reduced working capital for inventory ◦ Improved cash flow through quicker deliveries ◦ Accurate inventory records

  10. 10.  Business Process Re-engineering (BPR) is basically the fundamental re-thinking and radical re-design, made to an organizations existing resources. It is more than just business improvising. The activity by which an enterprise reexamines its goals and how it achieves them, followed by a disciplined approach of business process redesign. A method that supports this activity. It is an approach for redesigning the way work is done to better support the organizations mission and reduce costs. Reengineering starts with a high-level assessment of the organizations mission, strategic goals, and customer needs.
